To all whom it may concern:

Be it known that I, ROBERT Dawns, a citizen of the United States, residing in Philadelphia, Pennsyl- Vania, have invented certain Improvements in Spinning, Twisting, and Winding Machines, of which the:

following is a specification.

The object of my invention is'to' facilitate the operation of the rotativ'e members of the machine, to simplify the mechanism whereby such rotation iseffected, to reduce to a minimum the friction upon saidrota-tive members, to provide for the ready splicing of broken threads, without stopping the machine.

In theaccompanying dravvings:Figure 1- is a view, partly in side elevation and partly in section, of a spinning, twisting or doubling machine constructed in accordance with my invention; Fig. 2 is a plan view of the same; Fig. 3 is a sectional plan view on the line a-a, Fig. 1; Fig. 4 is a plan view, on an enlarged scale, of part of the mechanism shown in Fig. 1; Fig. 5 is a ning single strands and winding them upon spools or bobbins, or for winding upon each spool 0r bobbin a plurality of separate strands which have been twisted together by the action of the machine prior to such winding of the same. p

1., 1 represent the end frames of the machine and 2 a longitudinal /bar in which are formed the bearings for the spindles 3, the latter carrying the bobbins 4.

upon which the spun or twisted yarns are to be wound, only two of these spindles being shownin the present instance, although the operative machine will be equipped with a larger number of such spindles.

To a suitable bearing in the bar, near one end of the machine, is adapted a vertical shaft 5 upon which is splined a driving pulley 6, which can therefore rise and fall upon the shaft 5 but will be rotated by the latter in any of its various positions thereon. Suitably guided on the frame of the machine is a longitudinal bar or plate 7, to which .verti cal reciprocating movedevices common to this class of machine.

To the pulley 6 is adapted a belt 9 which passes arounda tightening sheave 10 mounted in bearings in tension.

section on the line bb, Fig. 4; Fig. 6 is a view similar to Fig. 4 but illustrating the apparatus as designed for the use of a' flat driving belt instead of a round drivment can be imparted by any of the traverse, motionv a cross head 11, the latter being adapted to suitable longitudinal guides 12'near one end of the bar or plate 7, and being connected to a weight 13 by means of a cord 14 passing over. a sheave 15 upon the plate 7, whereby the belt 5 'Between the pulley6 and the tightening sheave 10 the belt 9 engages a series of rings 16, one for each spindle3, and a series of belt-directing pulleys 17, 18

9 is constantly maintained underand 19, the pulleys 17 and 18 being so disposed that projecting flanges thereon will engage with projecting flanges on the rings 16, as shown in Figs. 5 and 7, so as to provide proper vertical support for said rings.- I

Starting with the draft side'of the pulley 6, Fig. 2, the

belt 9 passes first partly around a pulley 19, thence part way around a pulley 17 thence part Way around the first ring 16, thence part way around a second pulley '17,

thence part way around the second ring 16, thence part way around a third pulley 17 thence part way around the tightening sheave 10, and thence over the pulleys 18 and part way around a pulley 19 to the pulley 6.

The flanges of the pulleys 17 and 18 act as roller bearings for the rings 16, and said pulleys, eiccept those at the extreme end of the series, are subjected to the pull of the belt on one side of their axes, and to the push of the rings on the opposite side of the same, consequently,

as to these pulleys, spindle friction is practically eliminated and as, in a full sized machine, the intermediate pulleys are greatly in excess of those at the ends of the series, the aggregate friction is very much reduced. The number and disposition of the pulleys 18 may be varied as desired, or these pulleys may-even be dispensed with if means are provided for retaining the rings 16 in case the belt 9 breaks, it having been found in practice that the pulleys 18 are not necessary for the support of the ring when the machine is running, or the belt is subjected to tension. The number and disposition of the pulleys 17 is such that the driving belt passes around a considerable portion of the periphery of each ring 16, in order to exert the desired tractive force thereupon, the rings being free from any driving connection with the return run of the belt, so that any variations in slackness or tension of the driving and return runs otthe belt will have no effect upon the proper driving of the rings 16.

In Figs. 10 and 11 Ihave shown, in a diagrammatic way, two other arrangements of supporting and driving devices which are within the broad range of my invention, and these modifications may serve to suggest to thoseskilled in the art other modifications embodying the essential features of the invention.-

In the modification shown in Fig. 10, one of the pulleys 17 has been abandoned, a single pulley 17 serving to direct the belt around the ring, and producing an even greater length of tractive contact for said belt than is provided in the construction shown in Fig. 2.

In the construction shown in Fig. 11, the axes of the pulleys 17, are in a diametrical line passing through the axes of the rings 16, and the axes of the pulleys 18, are in diametrical lines at right angles thereto. The driving belt but half way around each ring 16, one of the pulleys 18 sewing to prevent lateral displacement of the ring against the pull of the belt, and the other serving to prevent lateral displacement of the ring in the opposite direction in the event of the breaking of the belt. In this construction, also, the return run of the belt passes between one of each pair of pulleys 17 and the corresponding ring 16, but it is not in driving contact with the ring, for even if it touches the latter, the contact is not such as to prevent the belt from slipping or sliding over the periphery of the ring in response to the take-up action of the sheave 10. Each ring 16 may have a fixed thread guide thereon, but I prefer to provide each ring with a flange 20, for the guidanee'of a traveler 20', the latter guiding the strand or strands to be spun or twisted and wound upon the corresponding bobbin 4, each bobbin passing through an opening 22 in the bar or plate 7, and each of these openings being surrounded by one of the rings 16. In order to materially reduce th drag upon the rings which results when said rings are compelled to rotate the bobbins through the medium of the threads, cords or strands which are being wound upon the latter, I rotate each of the spindles 3 in the same direction as the corresponding ring 16, though at a somewhat lower rate of speed, there being a frictional connection between the bobbin and the driving spindle which permits of the rotation of the bobbin at somewhat higher speed than the spindle, this additional increment of speed being derived from the rotating ring, and being, of course, much less than when the entire rotative movement of the bobbin is derived from the ring.

As shown in Figs. 1 and 3, the shaft 5 has a fixed pulley 23 which receives a belt 24, the latter passing part way around directing pulleys 25 suitably mounted upon the bar 2, and so disposed that one of the runs of said belt 24 will be caused to pass in driving contact with the periphery of each of the spindle pulleys 26, the relative diameters of these pulleys and of the pulley 23 being such that the number of revolutions of each spindle in a given time will be slightly less than the number of revolutions of the corresponding ring 16. A tightening pulley or sheave 27 receives the belt 24 and is acted upon by a suspended weight and chain, in order that it may at all times keep said belt in proper driving contact with the pulleys 26. Each of the pulleys I7 and 18 is mounted so as to be free to rotate upon a spindle 30, which passesthrough a slot 31, in the bar or plate 7, as shown in Fig. 8, and is threaded for the reception of a nut 21, whereby.it can be secured to the said bar or plate 7, the slot permitting adjustment of the pulley to proper position for supporting the ring 16, or into position which permits of the application or removal of said ring. Secured to or forming part of the hub ofeach of the pulleys 26, is a cup 32, with in- -ternally beveled flange, and this cup receives a disk 33,.which has operative connection with the lower flange of the bobbin 4, and has a beveled periphery in conscopes the disk or the flange maybe faced with leather or other material for increasing the frictional hold of one upon the other.

In order to permit of the ready splicing of any of the threads, without stopping the machine, 1 construct the ring and traveler device in such a way that the traveler. may be clutched to the ring and caused to rotate therewith when the thread is under tension, but will be released from the control of the ring when the thread breaks. One method of accomplishing this result is shown in'Fig. 5, the flange 20 having a depending pin 35 with which the lower hook of the traveler engages when the thread is under tension, and said traveler is lifted, as shown by dotted lines, said hook of the traveler dropping out of the path of the pinwhen the traveler falls, on the breaking of the thread, as shown by full lines. 1

Instead of driving the spindles 3 in the manner described they may be independently driven by belts from a longitudinal drum in the usual way, or fixed spindles may be employed.
